Clarifies the definition of floor area

This bill clarifies how "floor area" is measured for residential buildings under New York's Multiple Dwelling Law. It specifies that spaces with higher ceilings (e.g., over 12 feet) count multiple times toward total floor area, while excluding cellars, low attics, mechanical equipment spaces (except as noted), and outdoor features like balconies. Developers, building inspectors, and property owners using these measurements for compliance will be directly affected. The changes focus solely on standardizing calculation rules, not altering building requirements or regulations.
